Features
• High Speed Voltage Output . . . . . . . . . . . . . . . . . 300V/µs
The HA-2546 is a monolithic, high speed, two quadrant,
analog multiplier constructed in the Intersil Dielectrically
Isolated High Frequency Process. The HA-2546 has a
voltage output with a 30MHz signal bandwidth, 300V/µs slew
rate and a 17MHz control bandwidth. High bandwidth and
slew rate make this part an ideal component for use in video
systems. The suitability for precision video applications is
demonstrated further by the 0.1dB gain flatness to 5MHz,
1.6% multiplication error, -52dB feedthrough and differential
inputs with 1.2µA bias currents. The HA-2546 also has low
differential gain (0.1%) and phase (0.1 degree) errors.
The HA-2546 is well suited for AGC circuits as well as mixer
applications for sonar, radar, and medical imaging
equipment. The voltage output simplifies many designs by
eliminating the current to voltage conversion stage required
for current output multipliers. For MIL-STD-883 compliant
product, consult the HA-2546/883 datasheet.

Theory Of Operation
REF
The HA-2546 is a two quadrant multiplier with the following
three differential inputs; the signal channel, VY+ and VY-,
the control channel, VX+ and VX-, and the summed channel,
VZ+ and VZ-, to complete the feedback of the output
amplifier. The differential voltages of channel X and Y are
converted to differential currents. These currents are then
multiplied in a circuit similar to a Gilbert Cell multiplier,
producing a differential current product. The differential
voltage of the Z channel is converted into a differential
current which then sums with the products currents. The
differential “product/sum” currents are converted to a singleended current and then converted to a voltage output by a
transimpedance amplifier.

The scale factor is used to maintain the output of the
multiplier within the normal operating range of ±5V. The
scale factor can be defined by the user by way of an optional
external resistor, REXT, and the Gain Adjust pins, Gain
Adjust A (GA A), Gain Adjust B (GA B), and Gain Adjust C
(GA C). The scale factor is determined as follows:
SF = 2, when GA B is shorted to GA C
SF ≅ 1.2 REXT, when REXT is connected between
GA A and GA C (REXT is in kΩ)
SF ≅ 1.2 (REXT + 1.667kΩ), when REXT is
connected to GA B and GA C (REXT is in kΩ)
The scale factor can be adjusted from 2 to 5. It should be
noted that any adjustments to the scale factor will affect the
AC performance of the control channel, VX. The normal
input operating range of VX is equal to the scale factor
voltage.
The typical multiplier configuration is shown in Figure 2. The
ideal transfer function for this configuration is:
VOUT =
(VX+ - VX-) (VY+ - VY-)
2
0
+ VZ-, when VX ≥ 0V
, when VX < 0V
The VX- pin is usually connected to ground so that when VX+
is negative there is no signal at the output, i.e. two quadrant
operation. If the VX input is a negative going signal the VX+
pin maybe grounded and the VX- pin used as the control
input.

The open loop transfer equation for the HA-2546 is:
VOUT = A
13 VX +
+
The VY- terminal is usually grounded allowing the VY+ to
swing ±5V. The VZ+ terminal is usually connected directly to
VOUT to complete the feedback loop of the output amplifier
while VZ- is grounded. The scale factor is normally set to 2
by connecting GA B to GA C. Therefore the transfer equation
simplifies to VOUT = (VX VY) / 2.
Offset Adjustment
The signal channel offset voltage may be nulled by using a
20kΩ potentiometer between VYIO Adjust pins A and B and
connecting the wiper to V-. Reducing the signal channel
offset will reduce VX AC feedthrough. Output offset voltage
can also be nulled by connecting VZ- to the wiper of a 20kΩ
potentiometer which is tied between V+ and V-.
Capacitive Drive Capability
When driving capacitive loads >20pF, a 50Ω resistor is
recommended between VOUT and VZ+, using VZ+ as the
output (see Figure 2). This will prevent the multiplier from going
unstable.
Power Supply Decoupling
Power supply decoupling is essential for high frequency
circuits. A 0.01µF high quality ceramic capacitor at each
supply pin in parallel with a 1µF tantalum capacitor will
provide excellent decoupling. Chip capacitors produce the
best results due to the close spacing with which they may be
placed to the supply pins minimizing lead inductance.
Adjusting Scale Factor
Adjusting the scale factor will tailor the control signal, VX, input
voltage range to match your needs. Referring to the simplified
schematic on the front page and looking for the VX input
stage, you will notice the unusual design. The internal
reference sets up a 1.2mA current sink for the VX differential
pair. The control signal applied to this input will be forced
across the scale factor setting resistor and set the current
flowing in the VX+ side of the differential pair. When the
FN2861.6
November 19, 2004
HA-2546
current through this resistor reaches 1.2mA, all the current
available is flowing in the one side and full scale has been
reached. Normally the 1.67kΩ internal resistor sets the scale
factor to 2V when the Gain Adjust pins B and C are connected
together, but you may set this resistor to any convenient value
using pins 16 (GA A) and 15 (GA C) (See Figure 3).
provides stability and a response time adjustment for the
gain control circuit.
This multiplier has the advantage over other AGC circuits,
in that the signal bandwidth is not affected by the control
signal gain adjustment.

Video Fader
The Video Fader circuit provides a unique function. Here Ch B
is applied to the minus Z input in addition to the minus Y input.
In this way, the function in Figure 6 is generated. VMIX will
control the percentage of Ch A and Ch B that are mixed
together to produce a resulting video image or other signal.
Many other applications are possible including division,
squaring, square-root, percentage calculations, etc. Please
refer to the HA-2556 four quadrant multiplier data sheet for
additional applications.

Automatic Gain Control
In Figure 4 the HA-2546 is configured in a true Automatic
